' Specification. forming part of Letters Patent No. 39,327, dated July21, 1863.

'i'oall ughom'it may ctncerrt. I

Be it known that I, ,P. W. REID, of Birmingham, in the county ofAllegheny and State of Pennsylvania, have invented a new and ImprovedPreserve-Jar; and I do hereby declare that the following is a full,clear, and exact description thereof, reference being had to theaccompanying drawings,'making a part I of this specification, in whichFigure "l is a perspective view of the top or .mouth of my improved jarwithout the cover. Fig. 2 is a diametrical section through the cover ofthejar. Fig. 3 is a top view of the jar with its cover confined inplace. Fig. 4 is a sectional view through the mouth andneck of the jar,showingth'e cover seated therein.

-Fig. 5 is a perspective viewot' the cover of last from year to yearwithout renewing or repairing.

'The nature of my invention consists in con 1 structing the mouth of ajar and .the stopper thereof in such amanner as to obtain a screwpressure and fastening, and also a*wedged or tapering bearing, thusenabling me to secure thestopper in the mouth of thejar very firmly,

and at the same time to makea perfectly-tight joint, as will behereinafter described.

It also consists in constructing-a cylindroconical stopper with anannular recess on its taperingend adapted to receive and to retain inplace a rubber gasket or packing-ring,

'1 verse handle or finger plate, which is-depressed or let into aconcavity formed in the top of the stopper and used for applying thestopper to the jar, or for removing the same therefrom, as will behereinafter described. In the accompanying drawings, A repre- "sents thebody of the jar, only a part of which is represented. B represents thereduced neck of the jar, and O the enlarged flaring neck of, the same.This flaring mouth consists of two right and left circular and taperinggrooves, a a, which terminate at their ends in vertical spaces 1) b andvertical rim, 0. The lower surfaces, (2 d, of the grooves a a inclinedownward toward the neck ofthe jar and form the rounded and circularshoulder a, which is produced by spreading out the plastic glass inthe'mold in the operation of forming the upper portion of the mouth ofthe jar. The whole jar is made with this form of mouth in a moldsuitably adapted to the purpose, and the operation requires nouinisuallabor nor ingenuity in performing the operation.

The cover or stopper for the mouth of this depression, f, in its top,which is divided cenis molded with the stopper, as shown in Fig stopperhas two lugs, ii, projecting therefrom, which are situated opposite toeach other, and these lugs are formed with rounded ends, adaptv ed to bereceived by the right'and left tapering grooves a a in the mouth of thejar, as

. shown in Fig. Thedistance across thcstoppers from the extremity of onelug to that of I theother is slightly less thanthe greatest diameter ofthe mouth of'the jar. The stopper, with its lugs it, may therefore beslipped into the mouth of the jar (by passing the lugs down through thevertical spaces 1) b) and rested upon the shoulder c, and then turned,so that the lugs will pass into the grooves a. a and under the inclinedplanes thereof. The cylindrical portion h terminates in a tapering orbeveled portion of the stopper. The surface of this beveled portion adoes not, however, impinge case it would be necessary to grind thissurface, and also that against'which it would bear, (the shoulder 42,)which would add greatly to the expense of the jar; but, in lieu aroundthe beveled sides of the stopper, and

band, 1', as shown in Figs. 2, 4, and ,5, and bejar is made of acylindro-conical shape,with a trally by a fiat handle or finger-piece,that 3. The upper or cylindrical portion, h, of this portion, a, whichforms the valve or closing upon the surface of the jar, for if this werethe of this objectionable mode, I form a recess, 1),

in this recess I introduce an india-'rubber;'

v confined in its place. The stopper being completed, it is applied tothe jar in the following manner: The lugs ii are brought over the spacesb b, and the stopper slipped down into the mouth of the jar. This bringsthe rubber band or packing rin contact with the'rounded shoulder c onthe jar and the lugs z z opposite the widest ends of theirrespcctivegrooves a a, so that by giving thestopper a turn the lugs will pass intothese grooves and bearagainst the upper'or inclined surfaces thereof andgradually depress the stopper into its seat, which operation compressesthe rubber band and spreads itout over and around the shoulder (2 andmakes a tight'joint at this point.

To reinove the stopper from the jar it is turned backward; but as thecompressed rubber packing r willforcc the lugs hard up against the uppersurfaces of the grooves a a, it will be fouud'easier to depress thestopper and to start it in this 'way. As the grooves widen, the hearingwill be diminished, untilfinally the lugs will be brought into thespaces 5 b, when the stopper may be easily removed.

The fingerpicee'g isused as a handle, as

shown in Fig. 5, for holding and removing from the jar, and. while thisis the case there is no portion of the handle which is liable to'stantially as herein described.

Having thus described my invention, what I claim as new,-and desire tosecure by Letters Patent, is 1 1. The cylindro-conical. stopper, in.combi' nation witlra depressed, handle, 9, and logs it, constructed insuch a manner-with reference to the mouth of a jar that I coinbinewith ascrewpressure and fastening a wedge-bearing,-'subs'tantially asdescribed.

3. Although I do not claim-,- broadly,ascrewstopper and a rubberpacking-ring, I claim constructing the mouth'of a jar with taperinggrooves a 01, spaces b b, reduced neck B, 'and rounded or beveledshoulder e, in combination with a cylindro-conical stopper, and a rubberpacking-ring, 1', applied to the beveled edge thereof, so asto bear uponthe rounded shoulder e andv to form a tight joint, sub- 4.
